Abstract

A gas-barrier multilayer structure which comprises at least one gas-barrier layer and at least one resin layer. The gas-barrier layer comprises a composite resin (C) comprising: a polyamide resin obtained by condensation-polymerizing m-xylylenediamine and a linear aliphatic α,ω-dicarboxylic acid; and a phyllosilicate treated with an organic swelling agent. The resin layer comprises a thermoplastic resin (D) having a lower glass transition temperature than the composite resin (C). The gas-barrier multilayer structure is obtained by subjecting an unstretched layered product to stretching/thermoforming under specific conditions. The stretching/thermoforming under specific conditions is effective in inhibiting fine cracks which may be present in the resins from causing blushing or a decrease in gas-barrier properties. Thus, a multilayer structure excellent in transparency and gas-barrier properties is obtained.
